Abstract

Improvements in the floating valves of double effect for hydraulic shock absorbers, constituted by a crown of sheet steel, maintained freely by simple support between two concentric seats and that ensures by itself the flow control in both directions when taking support against one or another of said seats, characterized by providing a permanent passage, which remains open when the piston of the shock absorber is at rest, made in the form of a narrow circular slit, continuous or discontinuous, between a central washer of weak thickness and the inner orifice of the cited crown of sheet steel.
